Application ala Julyn,

Dirigible Headlight, of which the following is a specification. l f

This invention relates to headlights for motor vehicles, and more particularly to headlights of the dirigible type, it being the primary object of the invention to provide novel means for adjusting the headlights in horizontal planes.

A further object of the invention is to provide means for adjusting the headlights in vertical planes, novel means being provided for locking the headlights in their adjusted positions,

With the foregoing and other objects in view which will appear asthe description proceeds, the invention .resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood y.that changes in the precise embodiment of the' invention Vherein disclosed, may be made within the scope of what is claimed, without. departin 1 from the spirit of the invention.

Referring to the drawings F F igure" 1 is a side elevational view disclosing a motor vehicle in dotted lines, and showing the invention as applied/thereto,

a lamp arm Gezitending inner end thereof.` Y l Each lamp is supportedby bracketinclludmg an uppersection 8 and a lower section 9, which sections may `be secured together in 'any suitable manner, it being unA` derstood that the brackets are made sectional to permit the gears `and operating element to be positioned therein.`

The -lower section of each bracket is provided with an openingto accommodate the tapered plug 10, which is providedv with a central bore to` accommodate the tubular shaft 11 which has connection with the downwardly and wardly, there being provided' a ball 7on` the pinion 12, at one end thereof, the connection between the tubularshaft 11 and plug 10 be-v ing suchV as 'to permit the tubular shaft 11 to rotate freely.`

The bracket `also includes a curved mem ber 13 adapted to cooperate with the curved member 14 providing@ socket for the ball'- 7, which is provided with rows of teeth 1.5 formed thereon throughout a' portion of its circumference.

Disposed within the hollowshaft. 11 is a shaftlG which passesthrough' the pinion 12 and supports the worm'l, which worm is in mesh with the teeth15 to rotate the ball `7 in a vertical plane to accomplish the adjustment of thelamp associatedtherewith.' The pinion 12 is also in mesh with theteeth 15, and isdesignedv to rotate the ball?l in a horizontal plane to accomplish the adjustment of the lamp in a horizontal plane. In order that the shaft 16 will be supported against lateral movement, the bearing inem# ber 18 is provided and 'positioned in the upper end of the bracket, the bearing mem? ber being shown as having a recessed por-v tion to accommodate ythe end" 19 of the shaft 16. v

Associated with the brackets is a gear casing indicated at ,20, in which gear casing are mounted the Vshafts 21 and'22 respectively, the shaft 21` being provided with gear teeth meshing with the worm 2l thatis bolted or otherwise secured to the steering post` 25 sothat movement .of the steering post will result in a relative movement of the worm 24, to accomplish the movement of the shaft 21. The shafts 21 and'v 22 are1 supported in bearings 26 which are positioned in the end walls of thev casing 20L Mounted on the shaft 21 to move .therewithpisn pinion 27 which meshes with the pinion 28 which iii turn is in mesh with the pinion 29 supported by theshaft 22, the shafts 21 and 22 have connection withI the shafts l1, through the` flexible shaft 30 which are supported Vwithin the flexible housings 31 that have their ends vconnected to the bracket members 9 as by means ofthe collars 32, the opposite ends thereof beingconnected with the casing fas by means of the collars 33.

The shafts421 and 22 arehollow and accommodate the shafts 34 which have connection with the shafts 16 through the4 flexible shafts 35, whereby movement of the shafts 34 produces a relative movement of the worm V17 to rotate therb'all 7 and adjust the lamp associated therewith in a vertical plane. VThe inner ends of the shafts-34 have connection with the flexible shafts 36 which carry pinions 37 that are mounted `between the bracketmembers 38, there being provided a pinion 39 disposed between the pinions 37 so that rotary movement of the pinion 39 will impart rotary movement toV the pinions 37to rotate the flexible shafts 36. y A squared shaft 20 supports the pinion 39 and carries the winged head 41 on one end thereof', Awhereby the shaft 40 and its pinion 4() may be rotated. Supported by the member 41', which may be a part of the'instrument board is a clutch face 42Vthat cooperates with the clutch' member that is carried by the shaft 40, the coiled spring 44 being. interposed between one of the bracket members 38 and the clutch member 43 for normally'urging the clutch member into engagement with Athe clutch face 42 for locking the shaft 40 and its pinion, against movement. From the foregoing itwill be `seen that if it is desired to rotate the pinions 39 to adjust the lamps 5' in verticalplanes, the

operator forces the. winged head 41 inwardly, to disengage the clutch face 42 and clutch; member 43, whereupon 4the shafts 36 may be rotated to rotate the worm 17.

, It isy obvious that when the winged head 41 is released, the coiled spring 44 urges the heads46 connected tothe rod 47 that extends between the lamps. Suitable ball bearings 48 are provided'to permit of movement` ofthe heads 46 with respect to the bolts 45. Y

It might be further stated that in order to exclude dust or other foreign matter from the interior of the socket member, a flexible covering 49 is provided. which covering connects the socket member with the arms 6 as 'clearly illustrated by Figure 2 of the draw- Yings:-

Having thus described the invention, what is claimed as new is 1. In a dirigible headlight, a bracket, said bracket having. a socket, alamp supporting arm having a ballformed on one end thereof and disposed within` the socket, said ball having teeth formed on theperiphery thereof, a shaft extending through the bracket, said shaft carrying aworm at one end and having a pinion disposed thereunder, said worm and pinion adapted to cooperate with the teeth of the ball-to move the lamp in vario-us directions, and means for controlling the movements of the wormv and pinion.
